Composition of matter and method of making the same.



UNITED STATES MAURICE N. AISEN, OF CHICAGO, ILLINOIS.

COMPOSITION OF MATTER. AND IVIE'II-IOD OF MAKING THE SAME.

No Drawi ng.

To all whom it may concern:

Be it known that I, MAURICE N. AIsEN, a subject of the King of Roumania, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Composition of Matter and Method of Making the Same, of which the following is a specification.

My invention relates to a method of rendering glue and gelatin soluble in an organic solvent such as methyl or ethyl alcohol, and the resulting product.

In my application Serial No. 834,884 filed April 28, 1914, I have fully set forth the desirability of a sizing solution containing glue which when applied to a fabric will not shrink the fabric, and have described several methods of hydrolyzing glue to render it soluble in an organic solvent. As hydrolyzing agents I have used mineral acids such as nitric acid, hydrochloric acid, and sulfuric acid, as more fully described in my said application.

The present application is confined to the use of an alkaline hydrolyzing agent such as potassium or sodium hydroxid. As a. specific example of one mode of procedure, ten per cent. of potassium hydroxid, of the weight of glue to be dissolved, is-dissolved in two gallons of alcohol and the mixture heated to about 120 F. The glue is then added, with stirring, and the mixture heated to about 145 to 150 F. The mixture is heated at this temperature for about one hour or one hour and a half and then neutralized by the addition of a suitable acid either completely or to any desired degree which is not harmful to the glue or to the material treated. 1

Instead of first dissolving the alkaline agent in alcohol I may add said agent to the glue and after heating the same add the alcohol.

As it is difficult to define the-exact point of transition from glue to gelatin I have used the term glue as including gelatin, and as meaning animal albuminoids and glues of gelatinic basis which heretofore, so far as known to me, have been insoluble in alcohol, acetone, ether and other organic solvents.

Comes of this patent may be obtained for five cents each, by addressing the Commissioner of Patents Specification of Letters Patent.

Patented Nov. 28, 1916.

Application filed July 6, 1914. Serial No. 849,267.

The composition obtained by hydrolyzing the glue by an alkaline ggent and then dissolving it in an organic solvent may be used in ways known in the arts for which sizings are necessary. It has been used by me as a sizing in the manufacture of straw braid hats by which I have been able to materially reduce the cost connected with the sizing operation as, because of its non-shrinking quality, a relatively large number of hats may be sized at one time without the disadvantages incident to the use of a water solution of glue.

\Vhat I claim and desire to secure by Letters Patent of the United States is 1. As a composition of matter glue hydrolyzed by an alkali and dissolved in an organic solvent. I

2. As a composition of matter an alcoholic solution containing glue hydrolyzed by an alkali.

3. As a composition of matter a neutral alcoholic solution containing glue hydro lyzed by an alkali.

4. The method of making a solution containing glue consisting in first hydrolyzing the glue by an alkaline agent and then dissolving it in an organic solvent.

5. The method of making a solution containing glue consisting in first hydrolyzing the glue by an alkaline agent and then dissolving it in alcohol.

6. The method of making a solution containing glue consisting in first hydrolyzing the glue by an alkaline agent, then dissolving it in an organic solvent, and then neutralizing the alkali to the degree desired.

7. The method of making a solution containing glue consisting in dissolving in an organic solvent about ten per cent. of potassium hydroxid, of the weight of glue to be dissolved, heating the mixture and then adding the glue thereto.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
